Sometime last year computers at the U.S. Social Security Administration were hacked and the identities of millions of Americans were compromised. What, you didn’t hear about that? Nobody did.

The extent of damage is only just now coming to light in the form of millions of false 2011 income tax returns filed in the names of people currently receiving Social Security benefits. That includes a very large number of elderly and disabled people who are ill-equipped to recognize or fight the problem. It’s an impact pervasive enough that the IRS now has a form just to deal with it: Form 14039: Identity Theft Affidavit, December 2011.
